TEXTURECEL™ 20000 P BA

TEXTURECEL™ 20000 P BA is a high molecular weight sodium carboxymethyl cellulose (CMC) polymer that has significantly fewer gel impurities than many other commercially available CMC materials.  When lower gel particle CMC binders are used to make anode coating formulations for batteries, the overall energy density of these batteries is found to increase.  Thus, TEXTURECEL™ 20000 P BA is an extremely effective CMC binder material to use in anode coating slurries for lithium-ion batteries. 

When TEXTURECEL™ 20000 P BA is used as a binder for graphite lithium-ion battery anodes, it can improve the specific discharge capacity of the battery during very high C-Rates.  This in turn enhances charging speed.  Lithium-ion batteries made with TEXTURECEL™ 20000 P BA also see increased specific discharge capacity over multiple aging cycles, indicating that lithium-ion batteries made with TEXTURECEL™ 20000 P BA CMC binders have longer battery life.  TEXTURECEL™ 20000 P BA has a degree of substitution of 0.9 and forms solutions with a viscosity of 1,900–3,000 mPa·s at 1 wt% addition to water.
